{\large{\textbf{\center Abstract}}
This text elaborates on polarized light on robotic or human eyes. It goes
on about an enhancement on the eye, multiple photoreceptor to axon connection.

\section{\large Introduction}
The eye is a photo-chemical-electrical system with photons being absorbed
and transmitted to the axon receptors to generate a chemical action potential
that gets transcoded in a retro-imaginary way in an organism's brain.
\section{\large Lensing effects}

During embryogenesis the neural tube develops into the Central Nervous System
and its extensions. The eye is composed of a keratin layer, the lens of the eye.
Light gets captured on this lens and can be noticed by the eye's connected
brain after going through a neural (chemo-electrical) pathway.

\end{figure}

\section{\large Superposition on the eye}

A connection of the eye's optical pathway can be superimposed. This features
one or more neuron connections for the same bit of the eye. In this way, light
gets transduced several times on the same bit in the eye's virtual bitmap, 
which is the lens and its synapses.

Polarized light breaks on the lens as to provide colour. The depth of such
an image gets coded for several times in our brain and leads to several
possibilities. If the brain cancels out the refracted light this feature
does nothing. The other way, it is possible to see a Doppler shift of
the light, thus providing depth or a different colour. The mathematics
for this is based on refraction and Lorentz algebras. 

The time delay on the fluid-bitmap eye's lens provides for shifted light.

\section{\large Polarizers in an Liquid Crystal Display (LCD)}


An LCD screen transfers light across several layers. Before and after
the Liquid Crystals there is a filter film with vertical (front) and
horizontal polarizer (See figure 3.)

\end{figure}

It is clear that such a system can be extracted from the cornea with both 
filters of the LCD as a refractive system for fluid-bitmap eyes i.e. eyes
with dual axons for one ganglion photo-receptor. 

\section{\large Conclusion}

A fluid-bitmap eye system has a few properties which allow it to refract
light in several ways. It is not sure whether such eyes exist or not but
as seen with polarizing filters and such the question remains if this
could be of any use for robot eyes.
